What does the Bible say about being right with God?

The crucial question regarding how a person can be right with God is addressed in various scriptures, particularly in Psalm 15, where David asks, 'Lord, who shall abide in thy tabernacle? Who shall dwell in thy holy hill?' This underscores the central need for justification before a holy God. Since no one can stand before God based on their own righteousness, we must rely on Christ, who in his sinlessness meets the demands of God's law. He is our advocate and mediator, and through faith in Him, we receive His perfect righteousness, making us acceptable to God.
